Slow Light: Who said light always travel at c ???

Presented by Joe Mok (CUDOS)

Scientists throughout the world are racing in the research in what is commonly coined 'slow light' - light that travels at speeds significantly lower than c., or optical delay comparable to the duration of an optical pulse. This research promises to have impact on applications in a variety of fields from telecommunications (eg. optical buffers) to quantum computing.

Slow light has been observed in a variety of physical systems, from common optical devices like VCSELs and SOAs, to atomic systems such as ultra-cold atomic vapour.

In our research, we investigate slow light in fibre Bragg gratings: optical fibres with embedded nano-scaled structures.
